Lexis refers to the vocabulary of a language — the individual words and phrases that make up a text. Semantics is the study of meaning — how words, phrases, and whole sentences convey meaning. These two levels are conventionally studied together because they are inseparable in practice: the words a writer or speaker chooses (lexis) carry specific meanings and associations (semantics) that shape the reader's or listener's understanding. You cannot fully analyse why a word was selected without analysing what it means and connotes, so lexical analysis and semantic analysis are two angles on the same act of word choice.
Lexis is often the level students reach for first, because vocabulary is the most visible "stuff" of a text. The danger is that lexical analysis collapses into listing words. The disciplines that lift it from listing into genuine analysis are: identifying the word class of significant words; grouping words into semantic fields; distinguishing denotation from connotation; and explaining word choice in terms of register, audience and purpose. This lesson covers each of these tools in turn.
Understanding word classes (also called parts of speech) is fundamental to lexical and grammatical analysis, and naming them accurately is a basic AO1 expectation. Each word class performs a different function in a sentence:
| Word Class | Function | Examples |
|---|---|---|
| Noun | Names a person, place, thing, or concept | cat, London, happiness, information |
| Verb | Expresses an action, state, or occurrence | run, think, is, have, become |
| Adjective | Modifies or describes a noun | red, enormous, beautiful, complex |
| Adverb | Modifies a verb, adjective, or another adverb | quickly, very, extremely, however |
| Preposition | Shows relationship between elements (typically spatial or temporal) | in, on, at, between, during, through |
| Conjunction | Connects words, phrases, or clauses | and, but, because, although, while |
| Determiner | Specifies or quantifies a noun | the, a, this, some, every, my |
| Pronoun | Replaces a noun or noun phrase | he, she, it, they, who, this |
| Type | Description | Examples |
|---|---|---|
| Concrete | Refers to physical, tangible things | table, dog, rain |
| Abstract | Refers to ideas, qualities, states | freedom, beauty, anger |
| Proper | Names a specific person, place, or organisation (capitalised) | Shakespeare, London, NHS |
| Common | General, non-specific nouns | city, writer, hospital |
| Collective | Refers to a group | team, flock, committee |
| Mass/uncountable | Cannot be counted individually | water, information, furniture |
| Type | Description | Examples |
|---|---|---|
| Dynamic | Express actions or events | run, hit, write, eat |
| Stative | Express states, conditions, or feelings | know, believe, love, own |
| Auxiliary | Help form tense, mood, or voice (primary auxiliaries) | be, have, do |
| Modal | Express possibility, obligation, ability, permission | can, could, must, should, might, will |
| Copular/Linking | Link a subject to a complement | She is a doctor. He seems happy. |
Key Definition: Word class — the grammatical category a word belongs to, determined by its function in a sentence. The major word classes are noun, verb, adjective, adverb, preposition, conjunction, determiner, and pronoun.
A productive first move with any text is to gauge its word-class profile and its lexical density — the proportion of content words (nouns, lexical verbs, adjectives, adverbs) to function words (determiners, pronouns, prepositions, conjunctions, auxiliaries). Texts packed with content words feel informative, formal and effortful to read (a quality of much written, planned language); texts with a higher proportion of function words feel more relaxed and speech-like. Beyond density, the balance of word classes characterises a text: a passage dominated by abstract nouns foregrounds ideas and concepts and can feel intellectual or evasive; one dominated by dynamic verbs foregrounds action and energy; one thick with adjectives and adverbs foregrounds description and evaluation and typically signals a persuasive or promotional purpose. You do not need to count precisely, but naming the dominant pattern — "the extract is strikingly noun-heavy and abstract" — and explaining what it reveals about the text's focus and register is a strong, efficient analytical opening that integrates lexis with grammar from the outset.
A semantic field (sometimes called a lexical field) is a group of words that are related in meaning and belong to the same topic area. Identifying semantic fields is one of the most productive moves in analysis, because it converts a scatter of individual word observations into a pattern — and patterns are what reveal a text's dominant themes, preoccupations and attitudes.
Key Definition: Semantic field — a set of words grouped by meaning, all relating to the same topic or concept. For example, a semantic field of war might include: battle, troops, enemy, advance, surrender, casualties.
For example, a political speech might draw on a semantic field of unity (together, community, shared, united, collective, common) to promote social cohesion, or a semantic field of conflict (fight, battle, enemy, defeat, struggle) to present political opponents as adversaries and frame politics as combat. Sports journalism is notorious for importing the semantic field of war into match reports (bombarded, onslaught, defended, captured the points), a conventional metaphor that dramatises competition.
The real analytical pay-off comes from tracking semantic fields across a text to reveal shifts in tone, topic and attitude. A charity appeal might open with a semantic field of suffering (pain, hunger, despair, vulnerable) to establish need, then pivot to a field of hope (future, transformation, change, opportunity) to motivate action, the structural movement from problem to solution mirrored in the vocabulary. Spotting where a text changes its dominant field, and asking why at that point, is far more impressive than simply naming one field and moving on.
Semantic fields are also a key vehicle of representation, because the field a writer chooses imposes a particular frame on the subject. Describe a sportsperson through a semantic field of warfare and you cast their contest as a battle to be won by force; describe the same event through a field of artistry (graceful, elegant, composed, masterful) and you reframe it as performance and skill. A government policy described through a semantic field of control (crackdown, clampdown, enforce, tighten) reads very differently from the same policy described through a field of care (support, protect, help, safeguard). When you identify a dominant semantic field, the strongest follow-up question is therefore not just "what is the field?" but "what does this framing make the reader feel about the subject, and what alternative framing has been avoided?" That move turns a list of thematically related words into a claim about how the text positions its audience.
Every word has a denotation — its literal, "dictionary" meaning — and connotations — the associations, feelings, and cultural values it evokes. This distinction is arguably the single most important tool in lexical analysis, because most persuasive and evaluative language works by choosing words whose connotations do the rhetorical work while their denotations stay broadly the same.
Key Definition: Denotation — the literal, explicit meaning of a word. Connotation — the associations, emotional overtones, and cultural values a word carries beyond its literal meaning.
| Word | Denotation | Connotations |
|---|---|---|
| Home | A place where a person lives | Warmth, safety, family, belonging, comfort |
| House | A building for human habitation | Neutral, physical structure, property, financial value |
| Slender | Thin | Elegance, grace, attractiveness |
| Skinny | Thin | Negative — too thin, unhealthy, unattractive |
| Thrifty | Careful with money | Positive — sensible, prudent |
| Stingy | Unwilling to spend money | Negative — mean, selfish |
Notice that the word pairs above are near-synonyms denotationally but diverge sharply in connotation. The choice between such words is one of the most powerful tools available to writers and speakers, and one of the richest seams for analysis: ask why a writer chose home over house, slender over skinny, freedom fighter over terrorist. Each choice positions the reader to evaluate the same referent differently — a phenomenon central to the representation strand of Section A.
The linguist Geoffrey Leech, in his study of meaning, distinguished several types of meaning beyond the purely conceptual (denotational), including connotative meaning, social meaning (what a word signals about its user's social or regional background), and affective meaning (the speaker's feelings and attitudes). You do not need to reproduce his full scheme, but the underlying point — that "meaning" is multi-layered and a single word can carry conceptual, social and emotional meaning simultaneously — is worth holding in mind, because it licenses you to read a word's social and emotional resonance, not just its denotation.
Beyond formality on a simple scale, several specific lexical categories signal a text's relationship with its audience, and naming them precisely is rewarded:
| Category | Definition | Analytical significance |
|---|---|---|
| Jargon | Specialist vocabulary specific to a field or profession | Constructs expertise and an in-group; excludes non-specialists; assumes shared knowledge |
| Slang | Very informal vocabulary, often tied to a social group and short-lived | Signals group membership, youth or subcultural identity, rebellion against formality |
| Colloquialism | Informal, conversational vocabulary acceptable in everyday speech | Builds approachability and a casual, friendly tenor |
| Idiom | A fixed expression whose meaning is not deducible from its parts | "Kick the bucket," "spill the beans" — culturally bound; can signal informality or shared cultural knowledge |
| Cliché | An over-used expression that has lost its freshness | Can suggest lazy writing, or can be deployed knowingly for familiarity or irony |
| Archaism | An old-fashioned word no longer in everyday use | "Thee," "hither," "whilst" — common in older texts; can connote tradition, formality or ceremony |
The presence or absence of jargon is one of the clearest indicators of assumed audience knowledge: a medical leaflet for patients will explain or avoid jargon, whereas the same content written for clinicians will deploy it freely. Slang and colloquialism, conversely, are bids for solidarity and informality. A text that mixes registers — slipping slang into an otherwise formal context, or jargon into a casual one — is usually doing so deliberately, and the clash is what you analyse. Idioms and clichés are worth noticing because, although individually small, a cluster of them characterises a text's voice as conventional and familiar, while a deliberately fresh or defamiliarised expression foregrounds itself against that backdrop of the expected.
Figurative language (also called imagery or tropes) uses words in ways that depart from their literal meaning to create particular effects. It is not the exclusive property of poetry: advertising, journalism, political speech and everyday conversation are saturated with figurative language, and analysing it is central to textual analysis.
| Device | Definition | Example |
|---|---|---|
| Metaphor | Describes one thing as if it were another | "Life is a journey" |
| Simile | Compares two things using "like" or "as" | "Her voice was like velvet" |
| Personification | Attributes human qualities to non-human things | "The wind whispered through the trees" |
| Metonymy | Substitutes the name of an attribute or associated thing for the thing itself | "The Crown" for the monarchy; "Downing Street" for the government |
| Synecdoche | Uses a part to represent the whole or vice versa | "All hands on deck" (hands = sailors) |
| Hyperbole | Deliberate exaggeration for emphasis | "I've told you a million times" |
| Litotes | Understatement, often using a negative to affirm the positive | "Not bad" (meaning good); "She's no fool" (meaning she's clever) |
| Oxymoron | Combines contradictory terms | "Bitter sweet," "deafening silence" |
| Irony | Saying one thing while meaning the opposite | "Oh great, another rainy day" (when the speaker dislikes rain) |
The cognitive linguists George Lakoff and Mark Johnson (in Metaphors We Live By) argued that metaphor is not merely a decorative device but is fundamental to how we think. Conceptual metaphors such as ARGUMENT IS WAR ("She attacked my position," "He defended his theory," "Your claims are indefensible") structure our understanding of abstract concepts in terms of more concrete, physical experiences. The implication for analysis is powerful: when you find a metaphor in a text, you are often glimpsing a whole conceptual frame the text invites the reader to think within, and the frame both reveals and conceals — TIME IS MONEY ("spend time," "waste time," "invest time") makes time feel like a finite resource to be budgeted, but hides ways of experiencing time that have nothing to do with economy.
A particular cluster of figures works through saying less, or other, than is meant, and these are easy to misread if taken literally. Irony says the opposite of what is meant and depends on the reader detecting the gap between words and intention; litotes affirms something by negating its opposite (not unimpressive, no small achievement), often producing a dry, understated, characteristically British tone; hyperbole deliberately overshoots for emphasis or comic effect; and euphemism (treated more fully below) softens. Recognising these requires reading for implied meaning rather than surface meaning, which is why they sit on the boundary between semantics and pragmatics. When you analyse them, make the implied meaning explicit and explain how the reader is expected to arrive at it — through tone, context, or shared knowledge — because the effect of irony or understatement lies precisely in the reader being trusted to do that inferential work.
